  1. Implementing and Testing IPsec:NIST’s Contributions Sheila Frankel Systems and Network Security Group Computer Security Division NIST sheila.frankel@nist.gov

  2. Customers: IPsec Reference Implementation • IBM, Microsoft, Boeing, Nortel, Cabletron • AT&T, Lucent, GTE, America Online • NASA, Sandia, Lawrence Berkeley Lab • UC-Santa Barbara, Mich. Tech. U • CA Dept. of Justice, US Geological Survey • McGill U, St. Paul’s Hospital (Canada) • Small consulting cos, private consultants • Total to date: 540

  3. Customers: IPsec-WIT Interoperability Tester • IBM, Nortel, Intel, Cisco, Xedia • Cabletron, Frontiertech, Nokia, 3Com • Indus River Network, Cryptek • MIT, U of Wisc, Boston College, USC/ISI • Internet Initiative Japan, Korea Telecom • Total to date: 130

  4. What can NIST contribute? • Encourage rapid development and deployment of a significant technology • Facilitate ongoing inter-operability testing • Help vendors to develop secure, robust products • Enable smaller industry vendors to jump-start their entry into IPsec • Act as an “honest broker”

  5. Why Internet Layer Security? Implement once, in a consistent manner, for multiple applications Centrally-controlled access policy Currently used for Virtual Private Networks (VPNs) Industry-wide Networks (e.g., ANX) Will be used to protect Internet infrastructure

  6. Protections Provided by IPsec • Authentication • Integrity • Replay protection • Confidentiality • Traffic analysis protection

  7. Components of IPsec • Security Headers • Authentication Header (AH) • Encapsulating Security Payload Header (ESP) • Security Protection Negotiation • Internet Key Exchange (IKE)

  8. NIST’s Contributions to IPsec • Cerberus - Linux-based reference implementation of IPsec • PlutoPlus - Linux-based reference implementation of IKE • IPsec-WIT - Web-based IPsec interoperability test facility

  9. IPsec-WIT: Motivation • Inter-operability of multiple implementations essential for IPsec to succeed • Existing test modalities • Interoperability “Bake-offs” • Pre-planned Web-based interoperability testing • Needed: spontaneous Web-based testing

  11. Are our customers satisfied? “Thanks for the quick response! I wasn't even to the point of being worried yet - are you sure you're part of a gov't agency ?” --A.J. LaSalle Automation Tools Group Cabletron Systems
